FLUSH-TANK VALVE.

1o all whom t may concern:

Beit known that I, ELIJAH R. HILL, a c1t1- zen of the United States, and a resident of New Albany, in the county of Union and State of Mississippi, have invented a new and Improved Flush-Tank Valve, of which the following isa full, clear, and exact description.

This invention1 relates to Hush tank apparatus and has particular reference to the automatic valves for controlling the inlet supply pipes of such devices, this inventionconstituting an improvement on the structure covered by Letters Patent of the United States, No. 1,257,231, issuedto me on the 19th day of February, 1918.

Among the objects of the present inven- 4 tion is to simplify and improve the constructitl tion along the lines of eiliciency, reliability and` compactness, and with reference to the present improvements attention will be given te theaccompanying drawings in which Figure and spud connection indicating the automatic valve in side elevation.

Fig. 2 is a vertical sectional view through the center of the inlet valve.

Fig. 3 is a horizontal sectional detail on the line 3-3 of Fig. 2.

Fig. 4: is a vertical central section showing a slight modification from the form shown on sheet one; and

Fig. 5 is a horizontal section on the line 5-5 of Fig. 4.

rlhrough the bottom of the tank l0 projects a spud 11 having a flange 12 coperating with the upper surface of the tank bottom and having a threaded lower end upon which is screwed a locking nut 13 against the lower surface of said bottom whereby the spud is locked in fixed position with a Huid tight connection with the tank. The water supply pipe 14 is connected in any suitable manner with the lower end of the spud as by means of a coupling nut 15.

Secured in or to the upper portion of the spud and at itscenter in communication with the port 16 thereof is a nozzle 17 having a bore 17 rllhe upper end of this nozzle is cylindrical as shown at 17, while the lower or base portion thereof 17 b is square in cross section, as shown'best in Fig. 3. The portion 17 a is of the same diameter as the smallest diameter of the base portion but since it constitutes a reduction from the square portion it follows that the corners of the base Specification of Letters Patent. i

portion the outer surface of the upper part of the nozzle.

`The valve proper comprises a head 18 pref-f erably screw threaded uponthe upper end of a sleeve 19 and carrying within it a gasket or washer 20 coperating with the upper end of the nozzlel as a valve seat. `The sleeve, like the nozzle, is of straight and hence relal tively simple and cheap construction. The sleeve is in the form of a hollow cylinder the `interior diameter of which is"substan tially equal to the largest diameter of the square portion 17h of the nozzle but having a loose slidable lit therewith. There is, therefore, providedample space 21 between the nozzle and the wall of the sleeve for the in-` iiow of water. The upper end ofthe sleeve 1s preferably spaced and guided by means of` a pluralityl of lugs 22 `formed onone of the parts and cooperating with the adjacent wall of the other part, the lugs being shown inithis instance as being formed upon the inner wall of .the sleeve and cooperating with the cylindrical upper portion 17a of the nozzle. In addition to the action of the lugs it will be noted that the corners of the lower portion of the nozzle have a similar guiding action in coperation with the inner surface of the Vlower end of the sleeve.

23 indicates an elliptical yoke pivoted at t on one side of the nozzle and valve, the opposite end 25 of the yoke being embraced by the fork 26 of a bell crank lever 27 pivoted at 28 on the upper end of a pedestal 29 carried by or formed as an integral part of the Spud 1l. The yoke 23 loosely surrounds the sleeve 19 and is shown provided with oppositely arranged slots 30 into which project a pair of lugs 31 formed on opposite sides of the sleeve. A float ball 32 adjustably connected at 33 with the upper end of the bell crank 27 acts when buoyed upward by the water to automatically seat the valve and stop the inflow in the well known manner, the floating device being movable around the fixed pivot 28 causing through the short arm of the bell crank a powerful seating action on the yoke 23 which in turn acts through the lugs 31 to carry the valve downward. The parts thus far described are of a very simple construction well adapted for safe and reliable operation notwithstanding the fact that being normally submerged in water are subjected to rust, corrosion or deposition thereon of sediment or the project radially materially beyondA f tice. Y v

In Figs. 4: and 5 the spud 11 is fitted toV the tank and provided With an inlet pipe member.

like that is likely to interfere with the operation of such devices in the usualrpracconnection similar to the features shown in Figs; I and r2, but in this modification a lsingle Ypedestal 29 carried by the spnd affords fixed` pivots for both the bell crank 27 and the, yokel 23, the respect-ive pivots being indicated at 28 and 24:. The bell crank is of va double nature and is provided with a l-nk 84 .pivoted itt-35 tothe bell crank and at 36 to the inner end lof the yoke. vThe yoke in this :instance acts Vas a lever of the first class; the inner end 'of Which isdepressed by the -floati'b'all when the Water is vdischarged from the tank, whereby theV outer end of the yoke is lifted Ithereby *lifting the valve which is` indicated as of the same construction asv fully described in connection With the' first "set Yof Vfigures including the nozzle The yoke 2B in Vthis modi'ed for-In instead of pass-ing' around lthe sleeve 19 reaches only to the sides where it is provided with slotted 'ends 30', Vhile the valve struetnrein each form of the invention is adapted to eop'erate With `the nozzle or valve seat irrespective of any particular` 'extent of rot-ation that may be imparted to the nozzle While being` fixed to the Spud, the lugs -3l cooperating with thev slots of the yoke in either case will insure proper coperation between the valve and the valve actuating means.

I claim:

In a Hush tank valve, the combination of a spud having a standard carried by one side thereof, a bell crank pivoted to the standard, a float ball connected to the bell crank, a valve seat nozzle extending upward from the s'pud, the base portion of the nozzle being polygonal While the upper por tion thereof is cylindrical, `the diameter of the upper portion being the same as the smallest diameter of the base portion, a

Y valve fitted upon and slidable up and down along the nozzle, said valve comprising,` a. hollow cylindrical lsleeve of uniform cross section, a head fixed to the upper end of the sleeve and a packing member carried within the head and cooperatingdirectly With the valve seat, and means cooperating with the valve and actuated by the b'ell crank 'on the fall of the Water level in 'the tank to open the valve.
